Analysis Note

The following cations are harmonized with the ICH Q3D limits:
  • Cadmium (Cd): from <= 0.0001% to <= 0.000020%
  • Mercury (Hg): from <= 0.0001% to <= 0.000030%
  • Lead (Pb): from <= 0.0001% to <= 0.000050%
  • Copper (Cu) gets 1 NKS more: from <= 0.002% to <= 0.0020%
The batch values are set to 30% of the Option 1 limit in each case. The MiBio parameters TAMC and TYMC are set to statistical testing and analyzed only once a year (periodic testing).

Other Notes

Concentrated phosphoric acid is approx. 85% H3PO4 (aqueous).
